How to stop Drag and Drop bubbling?

I've looked everywhere and cannot seem to find a solution. I am using HTML5's native drag and drop features, which are working great, until I drag a card over another card and they're combining. I don't want them to combine but to drop under the next card.
I assume it's something to do with the appendChild or the fact the cards are within the droppable wrapper? But I can't seem to find another way... Any help?
The codepen is here: https://codepen.io/_and_why_/pen/RyVGPG
<div class="wrap__global">
<div class="wrap__col col__ideas" id="target" ondrop="drop_handler(event);" ondragover="dragover_handler(event);">
<h2 class="col__title">Ideas</h2>
<div id="card0" class="wrap__card" draggable="true" ondragstart="dragstart_handler(event);">
<h2>Dmmy Idea</h2>

<div id="card1" class="wrap__card" draggable="true" ondragstart="dragstart_handler(event);">

</div>
<div class="wrap__col col__prom" id="target" ondrop="drop_handler(event);" ondragover="dragover_handler(event);">

</div>
</div>
</div>
const card = document.querySelectorAll('.wrap__card');
const columns = document.querySelectorAll('.wrap__col');
function dragstart_handler(e) {
e.dataTransfer.setData('text/plain', e.target.id);
e.dropEffect = "move";
}
function dragover_handler(e) {
e.preventDefault();
e.stopPropogation();
e.dataTransfer.dropEffect = "move";
}
function drop_handler(e) {
e.preventDefault();
var data = e.dataTransfer.getData("text/plain");
e.target.appendChild(document.getElementById(data));
}

In case anyone else comes looking, I figured it out. I added the noAllowDrop function to the cards and now you can't drag on top of them.
<div id="card2" class="wrap__card" draggable="true" ondragstart="dragstart_handler(event);" ondragover="noAllowDrop(event)">
<h2>Dummy promise</h2>
<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Ex necessitatibus nobis quasi odit, harum quis culpa. Ad blanditiis deleniti officia, at ducimus ratione, aliquam, ullam, architecto eum tempora nam nulla!</p>
</div>
function noAllowDrop(ev) {
ev.stopPropagation();
}

How to display an image in an element from another element using jQuery

I want to select and display an image using jQuery.
I'm trying click on tile_details div and display tile__media image in col-md-6 with jQuery.
<div class="tile">
<div class="tile__media">
<img class="tile__img" src="https://s3-us-west-2.amazonaws.com/s.cdpn.io/70390/show-18.jpg" alt="" />
</div>
<div class="tile__details">
<div class="tile__title">
Top Gear
</div>
</div>
</div>
<div class="container-fluid" style="display:none">
<div class="row">
<div class="col-md-6">

</div>
<div class="col-md-6">
//Display Image
</div>
</div>
</div>

If I understand the question correctly, you want to get the image from the '.tile__media' div and set it to the contents of that div. If you give the div an identifier, this could be achieved through the following jQuery:
$(".tile__details").click(function(e) {
$('#imageDiv').html($('.tile__media').html());
});
jsFiddle
Update: If you want it to be dynamic, based upon the image you clicked upon, you could clone the image clicked into the div. The code is as follows:
$(".tile__img").click(function(e) {
$('#imageDiv').html($(this).clone());
});
jsFiddle

You've to use find() instead else it will take just the first instance of the li:first :
$(document).ready(function(){
$(".add-active").find('li:first').addClass("active");
});
Hope this helps.

$(".add-active").find('li:first').addClass("active");

jQuery: fadeOut <div> element with with a close button

I am trying to build a dashboard UI where I want to be able to close some panels. I tried several ways to use the "this" keyword to avoid hard coding everything but couldn't figure it out. I'm sure there has to be a much more effective way to do what I did but I did achieve my goal.
Can anyone enlighten me on what I could do different?

jQuery:
$(document).ready(function() {
$('div').on('click', '#close1', function () {
$('#div1').fadeOut();
});
$('div').on('click', '#close2', function () {
$('#div2').fadeOut();
});
$('div').on('click', '#close3', function () {
$('#div3').fadeOut();
});
$('div').on('click', '#close4', function () {
$('#div4').fadeOut();
});
$('div').on('click', '#close5', function () {
$('#div5').fadeOut();
});
});

Below is an example where the user clicks on .btn-close and then fades out the closest section. It's much easier to bind an event to an class instead of several id's.
Since we're listening to an event we can use $(this) within the event listener. It will return the element that was clicked (in this example the anchor). When we got the clicked element we can use [.closest][1] to find the parent element based on class. And then we can use fadeOut().
$(document).ready(function() {
// Listen to clicks on btn-close
$('.content-section').on('click', '.btn-close', function () {
// Get closest content-section and fade it out.
// $(this) will be the anchor with the class btn-close.
$(this).closest('.content-section').fadeOut();
});

What I want is when I click on li#product-1 , .description-container #product-1 appears.
Same thing if I click on li#product-2, etc.
I try something in jQuery but it does not work.

First, prepending #product- to the the ids of your li elements will give something like "#product-product-1", which won't match anything.
Even if we did correct that, you can't have multiple elements with the same id -- there's no differentiation li#product-1 from div#product-1. ids must be unique; best-case, you'll select the li itself since it's the first match.
Instead, add a data-... attribute to the lis, and use that:
$('.description').hide();
$('li').click(function() {
var id = $(this).data("target");
$('#product-' + id).show();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul>
<li data-target="1">Product 1</li>
<li data-target="2">Product 2</li>
<li data-target="3">Product 3</li>
<li data-target="4">Product 4</li>
</ul>
<div class="description-container">
<div class="description" id="product-1">

</div>

Firstly you are appending the li id to product- which means you're looking for elements called product-product-1, which don't exist. Secondly your HTML has duplicate id attributes on the li and the related div elements which is invalid.
A better approach would be to use the index() from the clicked li to find the related .description. Try this:
$('li').click(function() {
$('.description').hide().eq($(this).index()).show();
});
.description {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul>
<li>Product 1</li>
<li>Product 2</li>
<li>Product 3</li>
<li>Product 4</li>
</ul>
